SHADE-HOLDER FOR ELECTRIC LAMPS.

To ffl/l wwm. t may conce/ra.'

Be it known that we, WILLIAM H. Pinc'nn'r'r and JAMES F. MoRToN,citizens of the United States, and residents of Trenton, in the countyof Mercer and State of New Jersey, have invented a new and ImprovedShade- 'l-lolder for Electric Lamps, of which the following is a full,clear, and eXact description.

This invention relates to shade holders especially adapted for use inconnection with an ordinary incandescent lamp socket.

The invention has for its general objects to improve the construction ofshade holders so as to perfect diffusion of light, prevent dust andinsects from entering the globe, and at the same time providing` for thefree circulation of air around the lamp, the shade holder being ofcomparatively simple and inexpensive construction, reliable and efiicient in use, and so designed that it can be adapted for lamp socketsand shades of ordinary form.

A more specific object of the invention is the provision of a shadeholder having` screened Ventilating` apertures in combina tion with aprotector which encircles the lamp socket and rests on the shade holderin spaced relation thereto, whereby rain and dust are prevented fromentering the shade, although free space is provided for the circulationof air through the apertures of the shade holder.

With such and other objects in view, the invention comprises variousnovel features of construction and arrangement of parts which will beset forth with partieularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of theinvention and wherein similar characters of reference indicatecorresponding parts in both the views,

Figure 1 is a central vertical section of the shade holder; and

Fig. 2 is a plan view with a portion of the protecting ring or cap-piecebroken away.

Referring to the drawing, A designates an ordinary lamp socket, B theshade holder and C the shade.

The shade holder B comprises a sheet metal stamping in the form of acrowned late 1 having a central opening 2 at which is provided adepending screw flange 3, and

at the periphery is a depending` iiangc 'it having lugs 5 that carryscrews 6 which clamp the globe C to the shade holder. On

the under side of the shade holder 'is a screen 7 which is a piece ofwire mesh of such diameter as to fit within the flange Ll,

and this wire gauze has a central opening` 8 of such size that thescreen can be forced on the iange 3 and frictionallyremain thereon. Theshade holder is attached to the socket 2 by means of a threaded sleeve 9which, together with the shade holder, are common articles ofmanufacture.

In order to prevent dust andthe elements from entering the shade aprotector D is employed. This is in the form of a sheet metal cap orring 10 which is arched or dished and provided with a central openinglarge enough to slip over the sleeve 9, there being a downwardlyextending flange 11 at the opening, the edge of the flange being adaptedto bear on the top surface of the shade holder, whereby the protector issupported in spaced relation from the shade holder in order to permit ofthe free circulation of air through the shade. This protector D alsoserves to prevent direct light rays from passing out from the lamp, sothat a uniform diffusion of light is rendered possible.

The points of merit in the present invention are the perfect diusion oflight, dust and insect-proofness, ample ventilation for the lamp, andsimplicity and economy o cost, the invention being a device that can bereadily installed without any electrician, and placements made upondrops, cords or chains already in use.

From the foregoing description taken in connection with theaccompanyingdrawing, the advantages of the construction and method ofoperation will be readily understood by those skilled in the art towhich the invention appertains, and while we have described theprinciple of operation, together with the device which we now considerto be the best embodiment thereof, we desire to have it understood thatthe device shown is merely illustrative and that such changes may bemade when desired as fall within the scope of the appended claims.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. The combination of a lamp socket, a shade holder thereon havingVentilating ery of the member, means for attaching the holder to a lampsocket depending within the holder, and a screen having an aperture, theedges of which have a forced engage ment with the said dependinrattaching means, whereby the screen is held fixed With respect to theapertures of the said mci'nber.

l. The combination ogtI a lamp socket, a shade holder thereon and havingVentilating apertures, means fastening said holder to the socket andpresenting' a neck above said holder and an annular cap-like protectingapertures, means to secure said holder to the socket, and a devicesurrounding the socket and having means to support the saine on saidholder independentlyY of the fastening of the holder to thel socket, andserving to position said device over and spaced from the apertures ofthe shade holder, to prevent dust or rain passing through the aperturesWhile permitting a free circulation of air.l

2. The combination of a lamp socket, a shade holder attached thereto andhaving Ventilating apertures, an arched member surrounding the lampsocket and having a central aperture formed With a depending angeengaging the top surface of the holder, whereby the member extends overthe apertures of the shade holder and permits of a free circulation ofair through the apertures.

3. A shade holder comprising a member having a central opening andventilating apertures between the opening and periphsocket, the devicehaving a central opening to snugly receive said neck and having adepending flange at said opening for supportmg said device in raisedrelation to the tures thereof vvhile permitting the free circulation ofair through the apertures.
